Cards in this deck (14)

1WavePropagation of a disturbance which transfers energy from one point in space to another without the physical transfer of matter
2FrequencyNumber of complete cycles performed by a particle per unit time
3WavefrontLocus or imaginary line joining all points of the wave that have the same phase
4Phase (Ф)Angular measure of the fraction of a cycle that has been completed by an oscillating mass
5Phase differenceMeasure of how much a wave is out of step with another wave and how much 2 particles in the same wave are out of step with each other
6Progressive waveNet transfer of energy from one place to another
7Stationary waveNo net transfer of energy/energy propagation
8Mechanical waveRequires a mechanical medium to pass through
9Electromagnetic wavesDoes not require medium to propagate (3x108)
10Transverse waveWaves oscillates in direction perpendicular to direction of propagation of energy
11Longitudinal waveWaves oscillates in direction parallel to direction of propagation of the waveform
12IntensityRate of energy flow per unit area perpendicular to the direction of propagation of the wave
13PolarisationProcess by which a wave’s oscillations are made to occur in a single plane only
14Malus’ lawIntensity of a beam of plane-polarised light after passing through a polariser varies with the square of the cosine of the angle through which the polariser is rotated from the position that gives maximum intensity
